The ‘Divergent’ actress maintains a strictly organic beauty
regime and picked up one of her most unusual habits from a taxi
driver, who advised her to ingest a supplement of bentonite clay
to clean the heavy metals out of her system.

She explained in an interview with IntoTheGloss.com: “He was
African and was saying that, where he’s from, the women eat
clay when they’re pregnant … So, I’ve discovered that clay
is great for you because your body doesn’t absorb it, and it
apparently provides a negative charge, so it bonds to negative
isotopes.

“And, this is crazy: it also helps clean heavy metals out of
your body. My friend starting eating it and the next day she
called me and said, ‘Dude, my s**t smells like metal.’ She
was really worried, but we did some research together and
everything said that when you first start eating clay, your
bowel movements, pee, and even you, yourself, will smell like
metal.”

The eco-friendly actress has found natural remedies for every
Hollywood beauty trick, namely rinsing her mouth out with sesame
oil instead of getting her teeth whitened.

Shailene added: “I love a natural way to heal. You can do
something called ‘oil pulling’ where you swish coconut or
sesame oil in your mouth when you wake up and spit it out.

“It’s amazing! It really makes your teeth whiter, because
the plaque on your teeth is not water soluble, it’s
fat-soluble.”

The 22-year old star also made the surprising confession that
she only washes her short hair once a month.

She joked: “I only shampoo it like once a month – the
oilier, the better.”
